1 Claim.

This invention relates to improvements in a light Weight hasp lock having a sliding bolt to hold the hasp on the keeper. Such a lock is usually employed on light weight suit-cases or other containers to secure contiguously disposed parts.

The contiguous parts of light weight cases are usually made of material which permits such parts to bend relative to each other so as to move out of coi-planar relationship. With the hasp locks previously employed this so tilted the hasp with respect to the keeper as to break the lock ing action of the bolt and permit the hasp to swing open. Locks of this type are also usually made from sheet metal stampings and as a result the latch bar with which the latch on the bolt engages is easily deformed to permit the hasp to be pried away from the keeper without withdrawing the bolt. Furthermore, the outward strain on the keeper transmitted by the bolt, in, the previously employed locks, is concentrated at one location on the keeper and thus makes it easier to pry the keeper away from the part to which it is secured.

t is an object of this invention, therefore, to provide a hasp lock of this type which, with the hasp in locked position on the keeper, tends to maintain the contiguous parts held together by the lock in substantial co-planar relationship.

It is a further object of this invention to pron vide a hasp lock of this type in which the hasp may not be easily pried away from the keeper without withdrawing the bolt and in which outward pressure on the keeper from the latch bolt is so distributed on the keeper as to prevent concentration thereof at one of the holding prongs.

These objects are obtained by providing the keeper with both a forward and rearward latch engaging bar positioned substantially near the fastening prongs of such keeper and providing the bolt of the hasp with a forward and rearward latch which respectively engage the forward and rearward latch engaging bars, of the keeper when the bolt is in locking position. By reason of locking the locking bar to the keeper at two spaced places, the hasp while locked is restrained from tilting with respect to the keeper and the part to which the keeper is secured. This in turn prevents the part to which the hasp is hinged from springing out of its normal co-planar relationship with respect to the other part. 'The rearward latch engaging bar may be of bridgelike construction, i. e. joined to the body of the keeper at both ends. Such a latch engaging bar cannot be deformed or sprung so as to let the latch on the bolt slip out from engagement therewith. By reason of using two locking places on the keeper the strain of outward pressure is distributed more uniformly on the various fastening prongs of such keeper.

The novel features, which are considered characteristic of the invention, are set forth with particularity in the appended claim. The in vention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a specific embodiment when read in connection with the accompanying drawing in which:

Fig. 1 is a view in top elevation of a hasp lock embodying the present invention, parts being broken away and shown in section for the sake of clarity in illustration;

Fig. 2 is a sectional view taken on line 2 2 of of Fig. l showing the bolt of the hasp in unlatched position; and

Fig. 3 is a View similar to that of Fig. 2 with the bolt in latched position.

Except as hereinafter particularly described, the elements which comprise the hasp lock shown in the drawing are substantially identical with elements performing identical functions shown and described in Patents Nos. 2,382,756 and 2,402,- 309 oi Robert S. Wagner, et al., dated August 14, 1945 and June 18, 1946, respectively, and owned by the assignee of this application. While it is not so shown (for clarity in illustration) the hasp lock bolt may be locked in latched position by a key and the advantages set forth herein are equally applicable to a hasp lock having a key locked bolt.

The hasp lock is secured to two contiguously relate-d parts i l! and i2, for example the side walls of the body and cover of a light weight suitcase or other receptacle. A keeper Ill is secured to the part i2 and a hasp plate i6 is secured to the part i0. A hasp I8 is pivoted to the hasp plate i6 by a hinge pin 2t. The spacing is such that when the parts are brought into co-planar substantially edge-abutting relation, the hasp E13 may be swung about the pin 20 into proper engagement with the keeper I4.

The keeper Ui has a marginal flange 22 to which is secured a forward (to the right as viewed in the drawing) prong 24 and two spaced rearward (to the left as viewed in the drawing) prongs 26. These prongs penetrate through the part l2 and are clinched. as shown to hold the keeper in place. The wall of the keeper M is incised and a portion pressed inwardly (downwardly as viewed in the drawing) to provide a floor 28. A forward latch engaging bar 36 is formed by a rearwardly projecting portion on the forward incision which remains in the plane of such wall.

In many cases the parts I and I2 are so thin in section and made of such flexible material that they may be readily sprung out of co-planar relationship. If the part I2 were sprung in wardly of the part I6 the hasp I8 would be swung clockwise with respect to its forward end. This swinging if permitted would quickly break the engagement of the haspIB- with the'keeper I4. strengthen the locking of thehasp a rearward latch engaging bar 32 is provided. rIhe bar 32 consists of a bridge-like portion of the undepressed wall of the keeper I4 along the rearward incision. The marginal flange 22 is notched at 34 to provide an entrance from the rear to below such rearward latch bar. Locking shoulders 36 are also provided near each side of the keeper I4 to engage with lugs on the hasp I8 and prevent the hasp from moving rearwardly of the keeper when in latched position.

The hasp Iconsists of the customary housing pivoted to the hasp plate I6 by the hinge pin 29. This housinghas depending lugs 38 which in the locked position of the hasp project toward the floor 28 of the keeper I4 and abut against the locking shoulders 36 Vto restrainA the hasp I2 from movingrearwardly Vwith respect to the keeper. A sliding bolt 40 is held within the housing of the hasp byinturned lugs 42 and by a linger button 44 attac-hed to the bolt and slidable in a slot AEYin thewall of such housing. The bolt 40 is normally urged forwardly of the housing into the latchedV position shown in Fig. 3 by a spring 48. In somehasp locks this spring, as is described in the aforementioned patents, may be also utilized to lock the bolt in latched position. The bolt 40 has a customarily shaped forward latch 50 having` a camming surface adapted to engage with the end of the forward latch bar 36 tocam the bolt'd rearwardly as the, hasp` I8 is pushed inwardly toward the keeper I4. When the end of theforward latch 56 passes the inner edge ofA thelatch engaging bar 36, spring 48 will automatically force the bolt 46 into the latched position shown in Fig. 3.

As previously explained, the keeper I4 has a rearward latch engaging bar 32 to prevent a swinging of the hasp Irelative to the keeper I4. Therefore, vthe bolt 49 is provided with a rearward latchlVA adapted to engage with the rearward latch engaging bar 32 whenthe hasp I8 and bolt 4I) are in Ylocked position. This provides a double engagement'between the bolt 49 and the keeper- I4 at spacedplaces with the results of preventing such relative swinging (and consequently keeping the parts I0 and i 2 in coplanar relationship) and of strengthening interconnection between hasp andkeeper lock so To prevent such swinging and to also l that the hasp I8 may not be readily pried outwardly (upwardly as viewed in the drawing) of the keeper I4 when the bolt 40 is in latched position. The rearward latch engaging bar 32 being in the form of a bridge extending between the body of the keeper 22 will not be easily bent even though the keeper be made as a sheet metal stamping. The prongs 2B are positioned on opposite ends of the rearward latch engaging bar 32 and hence any outward pressure applied to the bar 32 will be distributed on both such prongs. Also any outward pressure applied at the same time to the forward latch engaging bar 39 will be distributed to the prong 24. Thus outward pressurebn the keeper I4 is more uniformly distributed on allrthree spaced prongs and there is less opportunity for one prong to receive most of such pressure and open up as a result thereof.

Although only one embodiment of the invention is shown and described herein, it will be understood that this application is intended to Ycover such changes or modifications as come within the spirit of the invention or scope of the following claim.
